Bakar (Arab J Geosci 14:763, 2021) presented a comprehensive study to answer some questions regarding the origin of cherts and selective silicification of Eocene and Messinian host rocks. Silicification is one of the most significant diagenetic processes influencing the evolution of sedimentary rocks, especially carbonates and evaporites, which makes this study interesting. A large number of sedimentologists, stratigraphers, petroleum geologists, and other related fields are interested in studying silicification owing to the potential information that study of silicification might provide on paleogeography, paleoceanography, stratigraphic correlations, the diagenetic history of carbonate rocks, and other topics. However, I have some comments on some points stated in the paper of Bakar (Arab J Geosci 14:763, 2021).
